I have a new Vevor S4040 with a 400 x 400 workspace CNC. Just got it and in Gsender I clicked the Flash button...bad idea...everything went very bad. Learned about the $ codes and set them up best I could. Everything is working except for the size of things I'm trying to carve, or even move the spindle. The distance is WAY off. I clicked on jog 20mm and it went 80.12mm. A one inch circle came out 3.154 inches. Any idea what I'm doing wrong? New at this and not very good at it. Help!
Recalibrate your steps per mm (about 25% of current values, 20/80=1/4=0.25x) : Grbl v1.1 Configuration
I just saw a video that showed me that I multiply "Steps per minute" x Expected Travel Distance then divide it by the Actual Travel Distance. It worked exact. But now the spindle moves SOOOO slow. Any idea how to fix that?
